I had taken my 05 dmax into the shop with what I think was gelling. they said that Whatever fuel pressure i should be running (I forgot) I was only running about 1400 psi at the filter. They changed the filter under warranty (I already had the new filter recall done) I also told them about the parking lot surge along with the fuel filter % on the DIC they also took care of all of this at no charge. they left me with a slip of paper. This paper was a snap shot of the TIS 2000 system screen stating what they done it has ID numbers ,Current #, and a selected # along with a discription of the calibrations they did. Is this common for them to show you this?
